                This Annual Report on Form 10-K includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements are based on the Company’s current expectations and projections about future events. These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions about the Company and its subsidiaries that may cause actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements.

                These forward-looking statements include statements with respect to the Company’s vision, mission, strategies, goals, beliefs, plans, objectives, expectations, anticipations, estimates, intentions, financial condition, results of operations, future performance and business of the Company, including but not limited to, (i) projections of revenue, costs of raw materials, income or loss, earnings or loss per share, capital expenditures, growth prospects, dividends, capital structure, other financial items and the effects of currency fluctuations, (ii) statements of plans and objectives of the Company or its management or Board of Directors, including the introduction of new products, or estimates or predictions of actions of customers, suppliers, competitors or regulatory authorities, (iii) statements of future economic performance, (iv) statements of assumptions and other statements about the Company or its business, (v) statements made about the possible outcomes of litigation involving the Company, and (vi) statements preceded by, followed by or that include the words “may”, “could”, “should”, “looking forward”, “would”, “believe”, “expect”, “anticipate”, “estimate”, “intend”, “plan”, or the negative of such terms or similar expressions. These forward-looking statements involve risks and uncertainties which are subject to change based on various important factors. Some of these risks and uncertainties, in whole or in part, are beyond the Company’s control. Factors that might cause or contribute to such a material difference include, but are not limited to, those discussed in this Annual Report on Form 10-K, in the section entitled “Risks Particular to Our Business.” Shareholders are urged to review these risks carefully prior to making an investment in the Company’s common stock.

                The Company cautions that the foregoing list of important factors is not exclusive. The Company does not undertake to update any forward-looking statement, whether written or oral, that may be made from time to time by or on behalf of the Company

|  |   | Disaster Management Simulation. During fiscal 2005 we entered into numerous contracts for driver trainer simulators. These included an advanced, interactive virtual-reality based airport ground simulator for the Nashville, TN airport and a simulator for the Airside Operations Training Facility at Minneapolis-St. Paul International Airport. Additionally, we were selected by the Maryland Aviation Administration to perform airport certification and emergency drill training at the Baltimore- Washington International Airport. Exercises included three different scenarios: a security breach, a bomb detection/explosion and a hazardous material spill. And recently we were selected by the South Korean National Fire Academy to provide a virtual-reality based system for training firefighters in South Korea. We will continue to enhance product applications by adding additional software objects and increasing interactivity between the various scenarios. |

|   | During fiscal 2005 we successfully factory tested and shipped the Authentic Tactical Flight Simulator Model 400 (ATFS 400), which we believe is the world’s first ground-based simulator capable of creating an authentic simulated tactical maneuvering environment. Utilizing proprietary centrifuge and simulation technology, high-fidelity models of the airplane’s dynamic performance, the threats experienced by an aircraft in combat and other battle space factors are integrated into the motion controls to create a fully authentic flight environment for any specific combat aircraft. |

|   | We continue to evolve the technology in our GAT-II® General Aviation Trainers and our GYRO line of spatial disorientation devices. During fiscal 2005 we shipped a GYRO-IPT to the U.S. Air Force Research Laboratory (AFRL) to support sustained operations research and development of fatigue countermeasures. We also received an order from the United States Corps of Engineers for a Pilot Selection System to be installed in an international aeromedical center which will incorporate nine GAT simulators and be capable of developing an objective composite profile of pilot candidates. |

| **Customers**

In the current fiscal year and throughout most of our history, we have made a substantial portion of sales to a small number of customers that vary within any given fiscal year. We do not depend upon repeat orders from these same customers. We sell our aircrew training systems principally to U.S. and foreign governmental agencies. We sell sterilizers and environmental systems to commercial and governmental entities worldwide. 

In fiscal 2005 only one customer represented 10% or more of sales, the Royal Malaysian Air Force, which generated $3,388,000 or 12.2% of total sales. We do not have any relationship with this customer other than as a customer. We expect to continue to conduct business with Malaysia in fiscal 2006, albeit at a much reduced level.

**Foreign and Domestic Operations and Export Sales**

During the fiscal years ended February 25, 2005, February 27, 2004 and February 28, 2003, approximately $2,904,000 (10%), $1,717,000 (7%) and $4,626,000 (11%), respectively, of our net revenues were attributable to contracts with agencies of the U.S. Government or with other customers who had prime contracts with agencies of the U.S. Government. 

During the fiscal years ended February 25, 2005, February 27, 2004 and February 28, 2003, $12,912,000 (47%), $15,421,000 (59%) and $14,805,000 (34%), respectively, of our net revenues were attributable to export sales. Our customers’ obligations to us with regards to export sales are normally secured by irrevocable letters of credit based on the creditworthiness of the customer and the geographic area of the world in which they are located. 

During the fiscal years ended February 25, 2005, February 27, 2004 and February 28, 2003, $11,998,000 (43%), $8,857,000 (34%), and $23,692,000 (55%), respectively, of our net revenues were attributable to domestic sales to customers other than the U.S. government. (See “Note 10. Business Segment Information” to our consolidated financial statements in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference).

We do not believe that the distribution of our sales between foreign and domestic sales for any particular period is necessarily indicative of the distribution expected for any other period. 

We derive a large portion of our sales from long-term contracts requiring more than one year to complete. We account for sales under long-term contracts on the percentage of completion basis. See the section Critical Accounting Policies in the Management’s Discussion and Analysis of Financial Condition and Results of Operations and “Note 2. Summary of Significant Accounting Policies” to our consolidated financial statements in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference. 

Our U.S. Government contracts contain standard terms permitting termination for the convenience of the U.S. Government. In the event of termination of a government contract, we are entitled to receive reimbursement on the basis of work completed (cost incurred plus a reasonable profit). We customarily record the amounts that we anticipate to be recovered from termination claims in income as soon as those amounts can be reasonably determined rather than at the time of final settlement. All costs applicable to a termination claim are charged as an offsetting expense concurrently with the recognition of income from the claim.

**Manufacturing Facilities**

Our manufacturing facility is located on a five-acre site in Southampton, PA, northwest of Philadelphia. We have approximately 85,000 square feet devoted to manufacturing, assembly and testing. We have two centrifuge bays with specially designed foundations |

| for testing human centrifuges and other centrifuge-technology-based simulators and amusement rides. ETC is ISO 9001-2000 certified.

**Backlog**

Our sales backlog at February 25, 2005 and February 27, 2004, for work to be performed and revenue to be recognized under written agreements after such dates, was $19,084,000 and $16,914,000, respectively. In addition, our training, maintenance and upgrade contracts backlog at February 25, 2005 and February 27, 2004, for work to be performed and revenue to be recognized after such dates under written agreements, was $2,232,000 and $2,637,000, respectively. Of the February 25, 2005 backlog, we have contracts for approximately $15,243,000 for aircrew training systems and maintenance support, including $3,422,000 for the Japanese Defense Agency and $1,746,000 for the Egyptian Air Force. We expect to complete approximately 75% of the February 25, 2005 backlog prior to February 24, 2006, the end of our 2006 fiscal year. Of the February 27, 2004 backlog, we completed approximately 79% by February 25, 2005.

**Competition**

Our business strategy in recent years has been to seek niche markets in which there is limited competition. However, in some areas of our business we compete with well-established firms, some of which have substantially greater financial and personnel resources than we have. 

Some competing firms have technical expertise and production capabilities in one or more of the areas involved in the design and production of physiological flight training equipment, environmental systems, and other specially designed products, and compete with us for this business. The competition for any particular project generally is determined by the technological requirements of the project, with consideration also being given to a bidder’s reliability, product performance, past performance and price. 

We face competition in the sale of the larger custom-designed industrial sterilizers both from other manufacturers and from our customers’ in-house production capabilities. 

We believe that we are a significant participant in the markets in which we compete, especially in the market for aircrew training systems where we believe that we are a principal provider of this type of equipment and training in our market area. 

**Compliance with Environmental Laws**

We have not incurred during fiscal 2005, nor do we anticipate incurring during fiscal 2006, any material capital expenditures to maintain compliance with federal, state and local statutes, rules and regulations concerning the discharge of materials into the environment, nor do we anticipate that compliance with these provisions will have a material adverse effect on our earnings or competitive position.

**Compliance with Export Controls**

Depending on the product, customer, location and the application or use, many of our aeromedical products require an export license from the U.S. Commerce or State Department. Although most of these licenses are readily obtainable in a reasonable timeframe, most of our international contracts for aeromedical equipment include the issuance of an export license as a “force majure” exception for any contract penalties or liquidated damages. 

**Employees**

On February 25, 2005, we had 232 full-time employees, of which four were employed in executive positions, 79 were engineers, engineering designers, or draftspeople, 47 were administrative (sales, sales support, accounting, etc.) and clerical personnel, and 102 were engaged principally in production, operations and field support. 

**RISKS PARTICULAR TO OUR BUSINESS**

**Our business is subject to numerous risks and uncertainties which could cause our actual operating results and developments to be materially different from those expressed or implied in any of our public announcements or filings including this Annual Report on Form 10-K for the year ended February 25, 2005. These risks and uncertainties include the following items. This list is not exclusive of all the risks and uncertainties associated with our business.** |
|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| **We have major litigation and claims in process and these require a significant amount of management time and effort. Additionally, legal costs are a major portion of our general and administrative spending, thus redirecting funds from other operating activities.**
            Legal and claims costs in fiscal 2005 were $3.9 million or 31% of total general and administrative spending. Although this spending level is expected to decrease in fiscal 2006, the cost of pursuing these suits and claims will remain a significant amount. 

**There is a risk of an unfavorable outcome in litigation and resulting potential negative financial impact on our operating results.**

          In one of the cases of commercial litigation currently in progress, we have been counter-sued for an amount in excess of $22 million. While we believe we have valid defenses to each of the counterclaims and intend to vigorously defend ourselves against these counterclaims, an unfavorable outcome could result in an adverse material effect on our financial position. With respect to the claim against the U.S. government, historically recoveries have usually exceeded the carrying value of claims. However, these claims require significant management time and effort and normally take multiple years to resolve. Also, there is no assurance that we will always have positive experience with regard to recoveries for our contract claims.

**Our sources of revenues are not consistent; in any given fiscal year a substantial portion of our revenues is derived from a small number of customers that may not be recurring customers in future years.**

                In any given fiscal year, a substantial portion of our revenues is typically derived from a small number of customers. For example, in fiscal 2005 we generated approximately 36% of our revenues from sales to four customers, the Royal Malaysian Air Force, the United Kingdom Ministry of Defense, the Army Corp of Engineers, and a domestic customer. In fiscal 2004, we generated approximately 22% of our revenues from sales to two customers, the Royal Malaysian Air Force and the United Kingdom Ministry of Defense. In fiscal 2003, we generated approximately 57% of our revenues from sales to two customers, the Walt Disney Company and the Royal Thai Air Force. We cannot be certain that our most significant customers will continue to order our products and services at the same level at which they have ordered them in the past. Due to the expensive nature and highly specialized market for our products and services, if any of these customers stops purchasing our products and services and we are unable to identify new customers in a timely manner, our business will be adversely affected.

**Our significant debt could adversely affect our financial resources and prevent us from satisfying our debt service obligations.**

                We have a significant amount of indebtedness and may also incur additional indebtedness in the future. We may not generate sufficient cash flow from operations, or have future borrowings available to us, sufficient to pay our debt. At May 6, 2005, our total indebtedness was approximately $14.1 million and our total stockholders’ equity was approximately $24.4 million.

                Our ability to make debt payments depends on future performance, which, to a certain extent, is subject to general economic, financial, competitive and other factors, some of which are beyond our control. Based upon our current level of operations and anticipated growth, we believe that cash on hand and available cash flow will be adequate to meet our financial needs. There can be no assurance, however, that our business will generate sufficient cash flow from operations to enable us to pay our debts or to make necessary capital expenditures, or that any refinancing of debt would be available on commercially reasonable terms or at all.

|                 A portion of our outstanding indebtedness bears interest at variable rates. Any increase in interest rates will reduce funds available to us for our operations and future business opportunities and will adversely affect our leveraged capital structure.

**We do not currently have a bank facility which can be used to borrow funds for operating purposes. Additionally, covenants and restrictions in our credit facility, and any additional changes in the facility amount or structure, could limit our ability to take certain actions and fund our operations.**

                During fiscal 2005 our bank took certain actions which effectively eliminated our ability to borrow cash under our existing agreement to support operations. Thus, we may need to obtain additional sources of capital in order to continue growing and operating our business. This capital may be difficult to obtain and the cost of this additional capital is likely to be relatively high. 

                Our credit facility contains significant financial and operating covenants that limit the discretion of our management with respect to certain business matters. These covenants include, among others, restrictions on our ability to: |

|                 We must also meet certain financial ratios and tests under our credit facility. If we do not comply with the obligations set forth in the credit facility, it could result in an event of default, and possibly the acceleration of the related debt and the acceleration of debt under other instruments evidencing debt that may contain cross-acceleration or cross-default provisions. Negative operating results would impact our future compliance with these covenants and could adversely affect our business.

**Our operations involve rapidly evolving products and technological change.**

                The rapid change of technology is a key feature of all of the industries in which our businesses operate. To succeed in the future, we will need to continue to design, develop, manufacture, assemble, test, market and support new products and enhancements on a timely and cost-effective basis. Historically, our technology has been developed through both customer-funded and internally funded research and development, and we expect this practice will continue to be required in the future. We cannot guarantee that we will continue to maintain comparable levels of research and development nor that this development will be customer-funded in the same ratio going forward. Reinvestment of operating funds and profits in an amount greater than currently earned may be required. Even so, we cannot assure you that we will successfully identify new opportunities and continue to have the financial resources required to develop new products profitably. At the same time, products and technologies developed by others may render our products and systems obsolete or non-competitive.

**Delays in the delivery of our products may prevent us from invoicing our costs and estimated earnings on uncompleted contracts.**

                In accordance with generally accepted accounting principles for long-term contracts, we record an asset for our costs and estimated earnings that exceed the amount we are able to bill our customers on uncompleted contracts. At February 25, 2005, $1.8 million of our costs and estimated earnings that exceeded our billings on uncompleted contracts related to two contracts with two different customers. We are not able to bill these amounts unless we meet certain contractual milestones related to the production, |

| delivery and integration of our products. Normally there will be a lag normally ranging from 24 to 36 months between performance and associated costs for these types of projects and billing and collection of payments. Our failure to meet these milestones by delivering and integrating our products in a timely manner may impact our ability to recover our costs and estimated earnings that exceeded our billings on uncompleted contracts, which could severely impact our cash flow. 

**In the event we suffer production delays, we may be required to pay certain customers substantial liquidated damages and other penalties.**

                The variety and complexity of our high technology product lines require us to deal with suppliers and subcontractors supplying highly specialized parts, operating highly sophisticated equipment and performing highly technical calculations. The processes of planning and managing production, inventory levels and delivery schedules are also highly complex and specialized. Many of our products must be custom designed and manufactured, which is not only complicated and expensive, but can also require long periods of time to accomplish. Slight errors in design, planning and managing production, inventory levels, delivery schedules, or manufacturing can result in unsatisfactory products that may not be correctable. If we are unable to meet our delivery schedules, we may be subject to penalties, including liquidated damages that are included in some of our customer contracts. While our actual losses have been minimal, we may incur substantial liquidated damages in the future in connection with product delays. 

**If the commercial simulation business conducted by our Aircrew Training Systems Segment declines, our sales will decrease.**

                We have no assurance that our commercial simulation business will continue to succeed. Although our commercial simulation business was minimal in fiscal 2005, this segment historically contributes to our gross revenues in each fiscal year. This business is subject to many risks including: |

| If we do not adequately address these risks, then our commercial simulation business may decline which will adversely affect our business.

**Our fixed-price and cost-reimbursable contracts may commit us to unfavorable terms.**

                We provide our products and services primarily through fixed-price or cost-reimbursable contracts. Fixed-price contracts provided approximately 94% of our sales for the fiscal year ended February 25, 2005. Under a fixed-price contract, we agree to perform the scope of work required by the contract for a predetermined contract price. Although a fixed-price contract generally permits us to retain profits if the total actual contract costs are less than the estimated contract costs, we bear the risk that increased or unexpected costs may reduce our profit or cause us to sustain losses on the contract. Therefore, unless there are customer-requested changes in scope or other changes in specifications which are reimbursable, we fully absorb cost overruns on fixed-price contracts and this reduces our profit margin on the contract. These cost overruns may result in us recognizing a loss on the contract. A further risk associated with fixed-price contracts is the difficulty of estimating sales and costs that are related to performance in accordance with contract specifications. Our failure to anticipate technical problems, estimate costs accurately or control costs during performance of a fixed-price contract may reduce our profitability or cause a loss.

                We did not have any sales for cost-reimbursable contracts for the fiscal year ended February 25, 2005. On a cost-reimbursable contract, we are paid up to predetermined funding levels determined by our customers on allowable incurred costs and generally a fee representing a profit on those costs, which can be fixed or variable depending on the contract’s pricing arrangement. Therefore, on a cost-reimbursable contract we do not bear the risks of unexpected cost overruns. U.S. Government regulations require that we notify our customer of any cost overruns or under runs on a cost-reimbursable contract on a timely basis. Should we be awarded any cost-reimbursable contracts in the future and incur costs in excess of the funding limitation specified in the cost-reimbursable contracts, we may not be able to recover those cost overruns.

**Cost estimates used to account for contracts under the percentage of completion method may vary over time and impact future performance under these contracts.**

                We record sales and profits on a significant portion of our contracts using the percentage-of-completion method of accounting. This means that we calculate a ratio of costs incurred to costs expected to be incurred for each fixed-price job and then |

| 9 |
|---|

| multiply that same ratio by the fixed-price contract value to determine total revenue to be recognized to date for each fixed-price job. As a result, contract price and cost estimates on fixed-price contracts are reviewed periodically as the work progresses, and adjustments are reflected in income in the period when the estimates are revised. To the extent that these adjustments result in a loss, reduction or elimination of previously reported profits, we would recognize a charge against current earnings, which could be material and have a negative effect on our business, financial condition or results of operations. Although we believe that adequate provisions for losses for our fixed-prices contracts are recorded in our financial statements as required under accounting principles generally accepted in the United States of America, we cannot assure you that our contract loss provisions, which are based on estimates, will be adequate to cover all actual future losses. 

**Our contracts and subcontracts that are funded by the U.S. government or foreign governments are subject to government regulations and audits and other requirements.**

                Government contracts require compliance with various contract provisions and procurement regulations. The adoption of new or modified procurement regulations could have a material adverse effect on our business, financial condition or results of operations or increase the costs of competing for or performing government contracts. If we violate any of these regulations, then we may be subject to termination of these contracts, imposition of fines or exclusion from government contracting and government-approved subcontracting for some specific time period. In addition, our contract costs and revenues are subject to adjustment as a result of audits by government auditors. We reflect any adjustments required by government auditors in our financial statements. Although we have thus far not been required to make any material audit adjustments, adjustments may be required in the future. In connection with our government contracts, we have been required to obtain bonds, letters of credit or similar credit enhancements.

**Our contracts that are funded by the U.S. government or foreign governments are subject to a competitive bidding process that may affect our ability to win contract awards or renewals in the future.**

                Government contracts generally are awarded to us through a formal competitive bidding process in which we may have many competitors. Upon expiration, government contracts may be subject, once again, to the competitive bidding process. We cannot assure you that we will be successful in winning contract awards or renewals in the future. Our failure to renew or replace government contracts when they expire could have a material adverse effect on our business, financial condition or results of operations. Our contracts with domestic or foreign government agencies are subject to competition and are awarded on the basis of technical merit, personnel qualifications, experience and price. Our business, financial condition and results of operations could be materially adversely affected to the extent that government agencies believe our competitors offer a more attractive combination of the foregoing factors. In addition, new government contract awards also are subject to protest by competitors at the time of award that can result in the re-opening of the competition or evaluation process, the award of a contract to a competitor, or the re-opening of the competitive bidding process. We consider bid protests to be a customary element in the process of procuring government contracts. Other characteristics of the government contract market that may affect our operating results include the complexity of designs, the difficulty of forecasting costs and schedules when bidding on developmental and highly sophisticated technical work, and the speed with which product lines become obsolete due to technological advances and other factors characteristic of the market. Our earnings may vary materially on some contracts depending upon the types of government long-term contracts undertaken, the costs incurred in their performance, and the achievement of other performance objectives.

**Our commercial contracts are subject to competition and strict performance and other requirements.**

                Although significant portions of our revenues are generated from the sale of our services and products in commercial markets, we cannot assure you that we will continue to compete successfully in these markets. Many of our commercial contracts contain fixed pricing. This subjects us to substantial risks relating to unexpected cost increases and other factors outside of our control. We may fail to anticipate technical problems, estimate costs accurately, or control costs during performance of a fixed-price contract. Any of these failures may reduce our profit or cause a loss under our commercial contracts. In addition, a significant portion of our revenues (49% in fiscal 2005) on fixed-price contracts is recognized on a percentage-of-completion basis. This means that we calculate a ratio of costs incurred to costs expected to be incurred for each fixed-price job and then multiply that same ratio by the fixed-price contract value to determine total revenue to be recognized to date for each fixed-price job. As a result, contract price and cost estimates on fixed-price contracts are reviewed periodically as the work progresses, and adjustments are reflected in income in the period when the estimates are revised. To the extent that these adjustments result in a loss, reduction or elimination of previously reported profits, we would recognize a charge against current earnings, which could be material and have a negative effect on our business, financial condition or results of operations.

                In connection with certain commercial contracts, we have been required to obtain bonds, letters of credit, or similar credit enhancements. We cannot assure you that we will be successful in obtaining these types of credit enhancements or that the credit enhancements available will be affordable in the future. |

|                 Under the terms of our commercial contracts, we typically must agree to meet strict performance obligations and project milestones, which we may not be able to satisfy. If we fail to meet these performance obligations and milestones, the other party may terminate the contract and, under certain circumstances, recover liquidated damages or other penalties from us which could have a negative effect on our business, financial condition or results of operations.

**There are certain risks inherent in our international business activities, which constitute a significant portion of our business.**

                Our international business activities expose us to a variety of risks. Our international business accounted for approximately 47% of our sales in fiscal 2005 and 59% of our sales in fiscal 2004. We expect that international sales will continue to be a significant portion of our overall business in the foreseeable future. Our international business experiences many of the same risks our domestic business encounters as well as additional risks such as: |

With respect to currency risk, where we have a contract which is denominated in a foreign currency, we often establish local in-country bank accounts and fund in-country expenses in the local currency, thus creating a “natural” currency hedge for a portion of the contract. 

                Our international transactions frequently involve increased financial and legal risks arising from stringent contractual terms and conditions and widely differing legal systems, customs and standards in foreign countries. In addition, our international sales often include sales to various foreign government armed forces, with many of the same inherent risks associated with U.S. government sales discussed in this Annual Report on Form 10-K.

**Legislative actions, higher director and officer insurance costs and potential new accounting pronouncements are likely to cause our general and administrative expenses to increase and impact our future financial condition and results of operations.**

                In order to comply with the Sarbanes-Oxley Act of 2002, as well as changes to the American Stock Exchange listing standards and rules adopted by the Securities and Exchange Commission, we have been required to strengthen our internal controls, hire additional personnel and retain additional outside legal, accounting and advisory services, all of which have caused and will continue to cause our general and administrative costs to increase. Although we have not experienced any claims, insurers have increased and are likely to continue to increase premiums as a result of the high claims rates they have incurred with other companies over the past year, and so our premiums for our directors’ and officers’ insurance policies are likely to increase. Changes in the accounting rules and auditing standards, including legislative and other proposals to account for employee stock options as a compensation expense among others, could materially increase the expenses that we incur and report under generally accepted accounting principles and adversely affect our operating results.

**Our sales backlog is not necessarily indicative of revenues that we will actually realize in fiscal year 2005 or at all.**

                We may not actually generate revenues in fiscal 2006 for all items included in our estimated backlog at the end of our 2005 fiscal year. At February 25, 2005, our sales backlog was $21.3 million. While we estimate that approximately 75% of this backlog is expected to be completed prior to the end of our 2006 fiscal year, we are not certain that these projects will be completed so that we can record these revenues by such date, or at all. During fiscal 2005 we shipped approximately 79% of our February 27, 2004 backlog. Our backlog includes the total value of all contracts less the revenue earned on those contracts through the measurement date. Many of our government contracts are multi-year contracts and contracts with option years, and portions of these contracts are carried forward from one year to the next as part of our backlog. Certain of our large contracts provide that we will not receive payment until the services under those contracts are requested and performed. We cannot assure that cancellations or adjustments in the terms of these contracts might not occur. |

| **Our operations could be hurt by terrorist attacks, war, disease and other activities or occurrences that make air travel difficult or reduce the willingness of our commercial airline customers to purchase our simulation products.**

                The demand for our various commercial simulation products and services is heavily dependent upon new orders from our commercial airline customers. In the event terrorist attacks, war or other activities or occurrences make air travel difficult or reduce the demand or willingness of our customers to purchase our commercial simulation products, our revenue may decline.

                Geo-political and other factors may also limit or restrict our employees’ ability to gain entrance to foreign locations to sell products or perform contract services. 

**There is limited trading activity in our common stock which could make it more difficult for our investors to sell their shares of our common stock.**

                Our common stock is listed on the American Stock Exchange. Our average daily trading volume during fiscal 2005 was less than 3,900 shares. This limited trading activity may make it more difficult for investors to sell larger blocks of our common stock at prevailing prices as there are generally a small number of participants in the market for our common stock and such sales may lower the market price of our common stock.

**The market price of our common stock may be volatile.**

                The market price of securities of thinly traded public companies has historically faced significant volatility. Although our common stock is traded on the American Stock Exchange, it does not experience a significant average daily trading volume. Accordingly, if one stockholder elects to either purchase or sell a block of our common stock, it may have an effect on the price of our common stock. In addition, the stock market in recent years has experienced significant price and volume fluctuations that often have been unrelated or disproportionate to the operating performance of particular companies. Many factors that have influenced trading prices will vary from period to period, including: |

| Demand for our products and services in each of the markets we serve can vary significantly from quarter to quarter due to revisions in customer budgets or schedules and other factors beyond our control. Due to all of the foregoing factors, our results of operations |

| may fall below the expectations of securities analysts and investors in a particular period. In this event, the price of our common stock may decline.

**Our officers and directors own a significant amount of our common stock which permits them to exert significant influence over the direction of our business and affairs.**

                As of May 6, 2005, our directors and executive officers own an aggregate of approximately 49.3% of our outstanding common stock. Accordingly, these persons, if they act together, will be able to exert control over the direction of our business and affairs.

**Item 2. Properties**

We own our executive offices and principal production facilities located on a five acre site in the County Line Industrial Park, Southampton, Pennsylvania in an approximately 100,000 square foot steel and masonry building. Approximately 85,000 square feet of the building is devoted to manufacturing and 15,000 square feet of this building is devoted to office space. The original building was erected in 1969 and additions were most recently made in 2001. We have pledged this property as collateral to secure the performance of our obligations under our revolving credit facility with PNC Bank, National Association and our subordinated debt financing with H.F. Lenfest. Additionally, we rent office space at various sales and support locations throughout the world and at ETC-PZL Aerospace Industries, our Polish subsidiary. 

We consider our machinery and plant to be in satisfactory operating condition. Increases in the level of operations beyond what we expect in the current fiscal year might require us to obtain additional facilities and equipment. 

**Item 3. Legal Proceedings**

               In April 2003, Boenning & Scattergood, Inc. (“B&S”) filed suit against us in the Court of Common Pleas in Philadelphia, Pennsylvania, seeking payment of $902,000 for financing fees allegedly due to B&S pursuant to the terms of an agreement for investment banking services which was entered into with a predecessor of B&S (the “B&S Agreement”). B&S alleged that it contacted the investors in our February 2003 financing transaction and that it earned the claimed financing fees pursuant to the terms of the B&S Agreement. We have responded to the complaint and have also filed a counterclaim for breach of contract and professional malpractice. We believe that we have valid defenses to each of the claims of B&S and intend to vigorously defend ourselves against these claims. We have had some settlement discussions but, as of the date of the filing of this Report on Form 10-K, no agreement had been reached. At this time, we are unable to predict the outcome of this matter.

                In June 2003, Associated Mezzanine Investors, LLC (“AMI”) filed suit against us in the United States District Court for the Eastern District of Pennsylvania seeking payment of $196,000 for costs, fees and expenses allegedly due to AMI pursuant to the terms of an agreement which we entered into with AMI (the “AMI Agreement”). AMI claimed that it located suitable investors for our February 2003 financing transaction and that it earned the claimed fees and is entitled to reimbursement of the claimed costs and expenses pursuant to the terms of the AMI Agreement. In March 2004, this suit was settled without any material impact on our results of operations.

                In            June 2003, Entertainment Technology Corporation (“EnTCo”),            our wholly-owned subsidiary, filed suit against Walt Disney World            Co. and other entities (“Disney”) in the United States            District Court for the Eastern District of Pennsylvania, alleging            breach of contract for, among other things, failure to pay all amounts            due under contract for the design and production of the amusement            park ride “Mission: Space” located in Disney’s Epcot            Center. In response, in August 2003, Disney filed counterclaims            against both EnTCo and us (under a guarantee) for, among other things,            alleged failures in performance and design in the contract. Disney            is seeking damages in excess of $65 million plus punitive damages.            Both EnTCo and we believe that we have valid defenses to each of            Disney’s counterclaims and intend to vigorously defend ourselves            against these counterclaims. At this time, discovery is completed,            summary judgment motions have been filed, and the case is scheduled            to be placed in the trial pool on June 27, 2005. Neither EnTCo nor            we are able to predict the outcome of this matter. 

Certain other claims, suits, and complaints arising in the ordinary course of business have been filed or are pending against us. In our opinion, after consultation with legal counsel handling these specific maters, all such matters are reserved for or adequately covered by insurance or, if not so covered, are without merit or are of such kind, or involve such amounts, as would not have a significant effect on our financial position or results of operations if disposed of unfavorably.             . |

| **Item 4.  Submission of Matters to a Vote of Security Holders**

No matters were presented to our stockholders during the fourth quarter of fiscal 2005.

**PART II**

**Item 5.    Market for the Registrant’s Common Stock and Related Security Holder Matters**

                On February 14, 2005 H.F. Lenfest, a Director of ETC, purchased 373,831 shares of unregistered common stock for an aggregate price of $1,999,995.85, or $5.35 per share, the closing price of ETC’s common stock on February 11, 2005, the trading day immediately prior to the purchase of the shares. None of these shares have been registered with the Securities and Exchange Commission or any state securities commission. These shares cannot be sold or transferred without complying with such federal and state securities laws. Under the American Stock Exchange listing rules, shareholder approval will be required for this transaction and this item will be included as a proxy item at our annual meeting in 2005. However, given the amount and nature of stock holdings by related parties, shareholder approval is expected to be received. The proceeds are being used for general corporate purposes.

                Additionally, see information appearing under the heading “Market for the Registrant’s Common Stock and Related Stockholder Matters” in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference. 

**Item 6.    Selected Consolidated Financial Data**

                See information appearing under the heading “Financial Review” in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference. 

**Item 7.    Management’s Discussion and Analysis of Financial Condition and Results of Operations**

                See information appearing under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference. 

**Item 7A. Quantitative and Qualitative Disclosures About Market Risk**

                We are exposed to various market risks, including changes in interest rates. Market risk is the potential loss arising from adverse changes in market rates and prices, such as interest rates and foreign currency exchange rates. We do not enter into derivatives or other financial instruments for trading or speculative purposes. We also have not entered into financial instruments to manage and reduce the impact of changes in interest rates and foreign currency exchange rates although we may enter into such transactions in the future. A portion of our indebtedness bears interest at rates that vary with the prime rate of interest. Accordingly, any increases in the applicable prime rate of interest will reduce our earnings. With respect to currency risk, where we have a contract which is denominated in a foreign currency, we often establish local in-country bank accounts and fund in-country expenses in the local currency, thus creating a “natural” currency hedge for a portion of the contract. . 

**Item 8.    Financial Statements and Supplementary Data**

                See the information appearing under the headings “Consolidated Financial Statements” and “Notes to Consolidated Financial Statements” in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference. 

**Item 9.    Changes in and Disagreements with Accountants on Accounting and Financial Disclosure**

                Not applicable. 

**Item 9A. Controls and Procedures**

                Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of February 25, 2005 (the “Evaluation Date”), and, based on this evaluation, our chief executive officer and chief financial officer have concluded that these controls and procedures were effective as of the Evaluation Date. There were no significant changes in our internal controls or in other factors that could significantly affect these controls subsequent to the Evaluation Date.

                Disclosure controls and procedures (as defined in Rules 13a-14(c) and 15(d)-14(c) under the Securities Exchange Act of 1934, as amended) are our internal controls and other procedures that are designed to ensure that information we are required to |

| **Committees of the Board of Directors              **

During the fiscal year ended February 25, 2005, the Board of Directors held three meetings. All members of the Board of Directors attended all of the meetings of the Board of Directors held while they were members of the Board of Directors except for Mr. Lenfest, who did not attend two meetings. 

During the fiscal year ended February 25, 2005, we had an Audit Committee consisting of Messrs. Kelley, Stephens and Anderson. Mr. Kelley serves as the Chairman and the “financial expert” (as defined by the American Stock Exchange) and has been designated as the Audit Committee Financial Expert as defined by the rules of the Securities and Exchange Commission. In addition, all members of the Audit Committee meet the financial literacy requirements of the American Stock Exchange and are independent under the rules of the American Stock Exchange. The Audit Committee held four meetings during the year ended February 25, 2005. Among other responsibilities, the Audit Committee meets (via face-to face or via telephone) with the external auditors to review and make recommendations to management concerning (if appropriate) the quarterly and annual financial results and the reports on Forms 10-Q and 10-K. The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of our independent accountants in their preparation or issuance of an audit report or the performance of other audit and review services. 

Messrs. Kelley, Stephens and Anderson also served on our Compensation Committee during the year ended February 25, 2005, with Dr. Stephens serving as Chairman. The Compensation Committee is charged with reviewing the compensation and incentive plans of officers and key personnel. This Committee met for its annual review in March 2005.

Messrs. Kelley, Stephens and Anderson also served on our Nominating and Governance Committee during the year ended February 25, 2005, with Dr. Anderson serving as Chairman. The Nominating and Governance Committee is charged with finding and recommending new Board members and with ensuring our compliance with all regulatory governance requirements. This Committee met for its annual review in March 2005.

Messrs. Kelley, Stephens and Anderson also served on our Committee to Recommend Directors Compensation. During fiscal 2005, our directors who did not serve as officers were paid a fee of $2,000 (either in cash or equivalent value of common stock of the Company) per quarter for attending Board of Directors and committee meetings. At a meeting subsequent to fiscal year end, the Board of Directors approved a compensation plan for both new and existing members which would include options to purchase common stock of the company at yet-to-be determined levels. 

**Code of Ethics**

We have adopted a Code of Ethics, which applies to our chief executive officer, chief financial officer, controller and other senior financial officers. We have also adopted a Company Code of Conduct that applies to our directors, officers and all employees. The Code of Ethics and the Company Code of Conduct were each approved and adopted by our Board of Directors in April 2004. The Code of Ethics and the Company Code of Conduct are posted on our website, which is located at *www.etcusa.com.* We will also disclose any amendments or waivers to the Code of Ethics or the Company Code of Conduct on our website.

In addition, we have adopted a Whistleblower Policy and an Insider Trading Policy, both of which are posted on our website.

**Compliance With Section 16(a) of the Exchange Act  **

Section 16(a) of the Securities Exchange Act of 1934 requires our officers and directors, and persons who own more than ten percent of a registered class of our equity securities to file reports of ownership and changes in ownership with the Securities and Exchange Commission (“SEC”) and the American Stock Exchange. Officers, directors and greater than ten percent shareholders are required by SEC regulations to furnish us with copies of all Section 16(a) reports they file. The rules of the SEC regarding the filing of Section 16(a) reports require that “late filings” of Section 16(a) reports be disclosed in our proxy statement |

| 17 |
|----|

| Based solely on our review of the copies of such forms which we received, or written representations from reporting persons that no Section 16(a) reports were required for those persons, we believe that, during the fiscal year ended February 25, 2005, our officers, directors and greater than ten percent beneficial owners complied with all applicable filing requirements.

**Item 13. Certain Relationships and Related Transactions**

                On February 19, 2003, we completed a refinancing of our indebtedness with the PNC Bank, National Association and H.F. Lenfest in the aggregate amount of $29,800,000. Pursuant to the terms of a Convertible Note and Warrant Purchase Agreement, dated February 18, 2003, between us and Mr. Lenfest, we issued to Mr. Lenfest (i) a 10% senior subordinated convertible promissory note in the original principal amount of $10,000,000 and (ii) warrants to purchase 803,048 shares of our common stock. As a condition to closing the financing, we appointed Mr. Lenfest to our Board of Directors. On October 25, 2004, Mr. Lenfest executed a limited Guaranty Agreement which guaranteed the Company’s $5 million Letter of Credit facility with PNC, and in connection therewith, we issued a Stock Purchase Warrant to Mr. Lenfest pursuant to which Mr. Lenfest was entitled to purchase up to 200,000 shares of our |

| common stock at an exercise price equal to the lesser of $4.00 per share or 2/3 of the average daily high and low closing price of our common stock during the 25 day trading period immediately preceding the date of exercise. On February 14, 2005 Mr. Lenfest exercised all of his outstanding warrants and received 1,003,048 shares of unregistered common stock. Additionally, also on February 14, 2005, Mr. Lenfest purchased 373,831 shares of unregistered common stock for approximately $2 million. Under the American Stock Exchange listing rules, shareholder approval will be required for this transaction and this item will be included as a proxy item at our annual meeting in 2005. However, given the amount and nature of stock holdings by related parties, shareholder approval is expected to be received. For a more detailed description of the financing provided by Mr. Lenfest and PNC, see the Liquidity and Capital Resources section of the Annual Report to Stockholders attached as Exhibit 13 to this Annual Report on Form 10-K and incorporated herein by reference.

                Prior to the consummation of the refinancing, ATAM, a shareholder and a holder of warrants to purchase 332,820 shares of our common stock, consented to the financing transactions with PNC and Mr. Lenfest including the below market issuance of warrants to Mr. Lenfest. As a result of its consent, ATAM waived, solely in connection with such issuance, the anti-dilution rights contained in its warrant. In exchange for ATAM’s consent and waiver, we issued to ATAM warrants to purchase an additional 105,000 shares of common stock. Except for the number of shares issuable upon exercise of the warrants, the new ATAM warrants had substantially the same terms as the warrants issued to Mr. Lenfest. As of the date that these warrants were issued to ATAM, it was the beneficial owner of greater than 5% of our common stock as determined in accordance with Rule 13d-3 under the Securities Exchange Act of 1934. In fiscal year 2005 ATAM exercised all its warrants and received a total of 437,820 shares of our common stock. For a more detailed description of the financing provided by Mr. Lenfest and PNC, see the Liquidity and Capital Resources section of the Annual Report to Stockholders attached as Exhibit 13 to this Annual Report on Form 10-K and incorporated herein by reference.

**Item 14. Information Regarding the Company’s Independent Registered Public Accounting Firm**

                Under            the Company’s Bylaws and the charter of the Audit Committee            of the Board of Directors, authority to select the Company’s            auditors rests with the Audit Committee of the Board of Directors.            Such selection is made through formal act of the Audit Committee.            It has not been and is not the Company’s policy to submit selection            of its auditors to the vote of the shareholders because there is            no legal requirement to do so. Grant Thornton LLP, an independent            registered public accounting firm, was the Company’s auditor            for the fiscal year ended February 25, 2005. Auditors have not been            selected for the current fiscal year. A representative of Grant Thornton            is expected to be present at the Annual Meeting and will be given            an opportunity to make a statement to the shareholders, if he or            she desires to do so. Grant Thornton’s representative will also            be available to answer appropriate questions from shareholders.
